SPECIFICATION forming part of Letters Patent No. 282,191, dated July 31,1883. Application filed November 14, 1882. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE HAYES, a resident of the city, county, andState of New York, have invented a new and useful skylight bar or rafterfor metallic skylights, con-j such manner. that it formsa verticalcentral portion, having lateral flanges at its upper e part formingledges for the support of glass plates, and at its lower part gutters tocollect and carry off the water of condensation and leakage. So far thisbar or rafter is composed of one piece of sheet metal folded upward, as

two halves, so that an under cap is formed of the same piece and nojoint exposed below,

and thereby all leakage between the two halves l or sides entirelyprevented.

as lead or copper-formed into shape section-. ally like a letter Y, ithaving a stem and two upwardly-spreading flanges or webs. The stem orlower web is placed down between the tion of the part of the bar belowthe glasssupporting ledges to a proper distance, and

thereto secured byany suitable means, so that it forms an upwardcontinuation thereof. The stem and flanges of the pliable metalaresingle, and not of doubled metal, and the flanges are intended to belocated above the glass, when in a structure, and, being of pliable orflexible material, are adapted to be readily curing the same againstleakage. hen re- The nature thereof consists in the pe The remainglazing isnecessary, the flanges may be readily bent upward to theirfirst position, allowing removal of glass and placing of new. Theflanges are again bent or flattened downward to secure the joints, asbefore. The pliable material thus used admits of its being pressedtightly upon the glass, fitting closely into any inequalities of theupper surface thereof and rendering the joint water-proof.

Pliable cap-plates formed of sheet metal doubled together are difficultof operation.

They cannot be dressed or properly flattened down upon the glass plates,fitting snugly thereto, without their breaking. They are also double theexpense, and, being of necessity of lead or soft copper, they arecomparatively more costly. Pliable cap-plates formed of sheet metaldoubled where they come in contact with the vertical portion of theskylightbar, and at the points where they are riveted, prove defectivethrough leakage, the doubling up of the cap forming a trough or gutterconducting the water to the leaky points. Be-

sides, the double thickness is a waste of material. In consequence ofthese difficulties, pliable caps have not heretofore come into use. Inthe. accompanying drawings, Figure 1 is a vertical section of the loweror galvanized portion of the bar or rafter. Fig. 2 is avertical sectionof the upper or pliable metal portion of the bar or rafter Fig. 3 is avertical section of the two parts of the bar or rafter in combinationprevious to glazing. Fig. 4 is a vertical section of the entire barafter glazing, the glass being shown in place and the joints covered.

A represents the lower portion of the bar or of. a a are the gutters, bthe vertical central portion, and c a lateral flanges forming ledges tosupport glass plates. (1 is the stem of the upper portion, and e e thetwo upwardlyspreading flanges thereof. The rigidity of the metal formingthe lower portion A, aided by its shape and construction, forms thesustaining element of the bar. The flexibility or pliability of theupper portion, B, affords ready means of securing the joints, whenglazed, from leakage by being pressed down thereon, and facilitatesreglazing when necessary. The
